PURITY SCANNERPurity inspection and sorting system for all kinds of XLPE pellets
www.sikora.netwww.sikora.net
The purity of XLPE pellets, as they are used for the insulation of medium, high, and extra-high voltages cables as well as for on- and offshore cables, is a decisive characteristic for the quality of the end product. Breakdowns that are caused dur-ing the discharge test due to contaminated material can easily cause costs in the 6-digit range. Therefore, the use of highly clean material as well as the continuous detection and sorting out of contaminated pellets before they get into the extrusion process is of essential importance.
With the PURITY SCANNER, SIKORA provides an unrivaled, user oriented system for a 100% online inspection and auto-matic sorting of XLPE pellets for raw material producers as well as for end user for example cable manufacturers.
Unique combination of X-ray and optical technologyThe PURITY SCANNER intelligently combines X-ray technol-ogy with a dual-axis optical system. This combination assures the detection of metallic and organic impurities of 50 μm in the pellet itself and on its surface to 100%. Contaminated pel-lets are detected and separated in order to assure that only pure material gets into the cable insulation.
The application of both technologies is unique and is exceed-ing previous solutions on the market. Due to the specially de-veloped X-ray technology, the PURITY SCANNER is the first system that inspects transparent and colored (e.g. black) pel-lets as well as semi-conductive XLPE material for impurities and sorts them out automatically.
Innovative Feeding SystemThe pellets are fed via an inclined, stainless steel vibrating channel. The material does not come into contact with the ambient air as the transport system is hermetically sealed. Absolute purity is guaranteed. The devices are designed for throughputs from a few kilograms up to several tons per hour* and can also easily be integrated into existing feeding sys-tems.
Integration of the system in the production lineCable manufacturers install the PURITY SCANNER between the pellet package (e.g. octabin or bag), separator and the hopper of the extruder. The feeding of the material is done by gravity or via a vacuum conveyor. The transport system of the PURITY SCANNER is hermetically sealed assuring that neither dust nor other contamination from the outside get into the flow of XLPE pellets. In addition, the transport system can be oper-ated with an overpressure.
With the PURITY SCANNER, the production process in the cable industry is improved significantly and, thus, the safety and life time of the cable is increased.
Your benefits- Increases the reliability of the cable - Guarantees long life span- Reduces costs by the elimination of scrap, repairs and claims
- Eliminates the risk of high voltage discharges

Cleaning ConceptWhen designing the PURITY SCANNER, it was the utmost priority to create a system that remains long-time clean. Accor-dingly, the transport system is integrated into an encapsulated housing with slight overpressure in order to prevent contamina-tion entering the system from the outside.
Application Cleaning ConceptIn the event that cleaning of the system is required, the system can be easily and quickly opened and cleaned. Furthermore, the Cleaning Concept was developed for customers who run different materials respectively colors and want to clean the system when changing the material.
In addition to cleaning, there is the possibility to exchange thecomplete transport system with a cleaned system.
